Lake-effect snow began falling in the Chicago area late Monday, the beginning of what turned out to be fairly significant snowfall in some areas.

As of 7 a.m. Tuesday, Chicago's two airports recorded about 7 inches of snow. As is typical with these types of weather systems, other areas received just a dusting of snow or nothing at all.

That band of heavy snowfall continues it's march eastward, but what's left in its wake are bitter cold temperatures. Temperatures on Tuesday, Wednesday and Thursday will be near zero with wind chill values as cold as minus 20 to 25 degrees.

Cook and Will counties in Illinois remained under a Lake Effect Snow Warning until 9 a.m. Tuesday. Lake County, Ind., remained under a Lake Effect Snow Warning until noon. A Lake Effect Snow Warning for LaPorte County, Ind., is in effect until 8 p.m.
